Y This invention relates to a railroad rail and wheel flange oiler unitand itis generally aimed to provide a simple, compact, durable andreliable construction which is capable of Aoiling bothv of said partssimultaneously and which is operable by passing rollingstock. n"

A particular object is'to providea novel construction which'is`.fastened to the rail and lso iitted and related as to be actuatedeither on straight runs or curves, avoids unfrom a reservoir l18 througha delivery pipe due lateral projection and obstructionwith respectY tothe rail and trackway, and is capable of maintaining its operativeposition in the event parts thereofshould become detached. v Anotherobject is to provide a new combination comprising a pump in freecommunication with a source of oil supply capable of lilling withoutatfectingvoperation, and a valve located between a discharge nozzle andthe pump to prevent back low ofthe oil.

A `further aim is to produce a Vnovel railembracing pipe section tocarry the nozzle. p Various additional objects and advantages'willbecome apparent froma consideration of the description following takenin connection with accompanying drawings illustrating an operativeembodiment.

In said drawings-j y Fig. 1 is a view illustrating'my invention in sideelevation operativelyassociated with a rail and its support. Fig. 2 is aplanvview of the parts of Fig. 1. 'Fig. 3 is a cross sectional Viewtaken on the line'3-3 of Fig. 1, a'car wheel being additionally shown.

Fig. 6 is a detail sectional view taken on the-'line 6-6 of. 2teillustrate the details of the pump, and Fig.y 7 'is a 4detail, partly inlongitudinal section and partly in side elevation, throughlthe checkvalve de-` vice employed. l i f In order to render the mounting andoperation of theV invention clear, have .shown a conventional railwayrailat 1() disposed von tie-plates 11 in turn spiked to ties 12, and acar wheel 13 to traverse the said rail 10.

, Referring to the parts constituting my invention, av horizontallydisposed nozzle 14.- is arranged yadjacent to or in Contact with 55 thewheel-flange 'side 15 of the railv and is provided with a multiplicityof ports or orifices 16, through which voil or other lubricant isdischarged upwardly against the rail-V head side of the ilange 17 ofsaid wheel 13.

The lubricant for nozzle 14 is supplied 19 comprising straight section20, in which a pump 21 is fastened, and end section 22. Nozzle 14 may beformed integral with the 65 end section 22 as shown. Y

The reservoir V18 is a relatively'long and attenuated vbody whichpartially enters the fishing space of the rail, as particularly shown inFig. 4.. vThis reservoir, in practicemay'm be Vapproximate-ily threeinches in diameter and six feet long, so that itwillcontain aconsiderable supply of oil or lubricant which may be supplied through anopening covered by a filling plug 19. The reservoir 18 may 7.5

be secured in place in any desired manner and, for instance, by cleatsor clamps 20', which partially embrace the reservoir 18, and are securedVin place by spikes 21', the latter alsopserving to secure adjacenttie-plates 8.0

vlin place.

Fipe section 20`- leads directly from `reser-V voir 18 to the cylinder'of the pump 21, which lis designated 22'. Cylinder 22 has a removabletop or closure 23 screw threaded 85 'thereto at 24. A piston 25 isoperable within cylinder 22', preferably having packing rings on itsperiphery, as at 26. Said'lpiston 25 is normally centrally located inthe cylinder 22', as shown in Fig. 6, and is held by means of coilspringsA 27 located on opposite sides thereof in abutment therewith, andoneabutting the base of the cylinder, and the other abutting the top 23.A piston rod 28 'is screw threaded at 29 to the piston or head 25 andvis slidably mounted through' a central opening 30Vinthe top 23. .A cap31, preferably of hardened steel to resist wear,

is screw threaded at 32 to thetop ofthe rod Y 28 and is locatedexteriorly of the=cylinder 100 22. Such cap 31 is adapted to be engagedand depressed by the wheel 13 as it traverses rail 10 so as to causeoperation of the pump. The screw threads 32 permit vertical adjustmentof the cap 31 so as to vary the throw of the piston 25, and such cap 31may be fastened in its different adjusted positions by means of abinding screw or equivalent element 33 carried by the cap.

The cylinder 22 has integral attaching plates or flanges `34, by meansof which they may be bolted, or otherwise fastened, as at 35, to the webof the rail, the pump structure accordingly partially fitting into thefishing space of the rail.

A series of short pipes and fittings 36, in detachable screw-threadedrelation lead from the cylinder 22 to the end pipe section 22 andinclude a ball choke or check valve device 37 as detailed in Fig. 7 Suchdevice 37 includes a hollow casing 38 screw threaded to the sec-tion 22and al nipple 39 screw thread- 'ed to the casing 33 and to the series ofcouplings 36. Nipple 39 is normally closed by a ball valve 40 whichseats against the same and is urged into and normally held in closedposition by means of an expansive spring 41 located within the abutmentand casing 38. Depression of the pump 31, in view of the fact that thelower portion of cylinder 22 is always in full or unrestrictedcommunication with the reservoir 18, forces a quantity of oil throughthe connections 36 and past the check valve 40, the valve 40 actingVautomatically to open to permit the oil to pass it and to closeautomatically to prevent return of oil to the pump.

End pipe section 22, as best shown in Fig. 3, extends under the rail 10,between ties, and then upwardly and in combination with the fittings 36over the base flange 42 at one side of the rail, fitting in a notch 43thereof, and at its other end extending upwardly and over the baseflange 42, as at 44, thence upwardly against the web of the rail, a't45, and thence outwardly to the nozzle 14.

As a result of the construction described, operation of the pump 21maintains end pipe section 22 and nozzle 14 full of oil which can notreturn, due to the presence of the check valve 40. As the car wheel orwheels 14 traverse the rail 10, each wheel at its periphery-or treadengages the cap 31, thereby depressing it and pumping a quantity of theoil from the reservoir through pipe section 20, cylinder 22, connections36, past valve 40, into pipe section 22 and thence into the nozzle l14,from which the oil escapes through `orices 16, thereby lubricating theinner surface of the wheel flange and by contact therewith, the side ofthe rail head. Thus it will be 'seen that the pump is normally inactiveand is operated by each wheel 13 which passes `over 'the same, the pumpautomatically being restored to normally inactive position after eachoperation by the springs 27.'

Although I have shown the invention applied to but a single rail, thesame may be used on both rails and the device arranged in transversealinement on both of the rails, or such devices Ymay be provided at anydesired interval, or intervals, along either or both rails.

It will be noted that the various parts constituting'the Vinvention orunit are interfitted in the fishing space of the rail and that the pipesection-22 rather closely conforms to the shape of or embraces the rail,which is important not only from the standpoint of compactness but toenable the parts to remain substantially in 'their .normal or attachedposition .if any of vthe parts should become detached. To aid inattaining this result, the `lower surface of the cylinder 22 ispreferably inclined as at 46 (see Fig. 3i) conforming with the angle ofthe adjacent portion of the base flange 42 of the rail, so as to rest onsuch portion if flange 34 should break or bolts 35 loosen.

Various minor changes may be resorted to provided they fall within thespirit'and scope of the invention.

In combination with a rail, a delivery pipe section arranged todischarge lubricant adjacent the head of the rail, said section beingdisposed transversely under the rail, thence upwardly and over the baseon both sides of the rail, -a nozzle on one terminal of the lpipesection and lubricant supply means connected to the other terminal ofthe pipe section.
